Polyester Water and Oil Repellent Needle Felt Filter Bag
After being processed with water and oil repellant treatments, the needle felt filter bag becomes suitable for use in damp environments. When compared to traditional filter bags, these polyester filter bags have an extended dust removal cycle, prolonged service life and no risk of dust blockage. This filter is also able to improve the airflow volume, save energy and money, and increase the working efficiency.
In order to ensure the filter bag is of the highest quality possible, we conduct a series of post processing tasks, including water resistance, oil repellency, static resistance and more. These techniques are suitable for both needle felt filtration cloths, 208 polyester flannel cloth, 729 glass fiber cloth and more.
